Answer:

Explanation:

The physical methods of separating mixtures are used in sorting a mixture of substances.

It requires no chemical changes occurring between their components and parts in any significant way.

Examples are:

  1. Decantation
  2. Filtration
  3. Sublimation
  4. Magnetism
  5. Centrifugation

The methods simply relies on the physical properties of matter.

Inessa05 [86]

The third launch ( with 300 N force) had  the greatest acceleration of the tennis ball

<h3>Further explanation  </h3>

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

\large{\boxed{\bold{a=\frac{\sum F}{m}}}

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

From the above equation it has been shown that the force acting on the object is directly proportional to its acceleration, so <em>the greater the force exerted on the object, the greater the acceleration of the object produced.</em>

Indicate whether each of the following would increase or decrease the rate of reaction
mote1985 [20]

The rate of a chemical reaction is affected by temperature, Catalysts, Suface area, Concentration.

<h3>Rate of reaction</h3>

The rate of a chemical reaction is the rate at which the concentration of reactant molecules decreases or the concentration of product molecules increases.

<h3>Factors effecting rate of chemical reaction </h3>

The factors that affect the rate of chemical reaction include:

  1. Temperature: increase in temperature increases reaction rate while decrease in temperature decreases reaction rate.
  2. Catalysts: the present of catalysts increase the reaction rate. Some catalysts decreases reaction rate and are known as negative catalysts.
  3. Surface area: increase in surface area of reactants increases reaction rate.
  4. Concentration: Increase in concentration of reactants increases reaction rate while decrease in concentration of reactants decreases reaction rate.

Therefore, the rate of a chemical reaction is affected by temperature, Catalysts, Suface area, Concentration.
